To 41-1 I who m it ma y concern:

Be it known that we, ALEXANDER Mc- GARY and Jons W. JEPSON, both citizens of the United States, residin in the city, county, and State of New fork, have invented new and useful Improvements in Means for Mounting and Driving Dynamos for Electric-Car Lightin and other Purposes; and in order that those skilled in the art may make and use the same we give the Our invention relates to the mounting and driving of dynamo-electric machines and is artioularly concerned with means for mountthe same on railway cars or other vehicles to be driven by the wheel or axle of the vehicle.

Our invention has for its objectto provide tin-improved construction or arrangement for mounting d namo-electric machines on em whereby t e disadvantages and difiimeans hitherto known or used For this purprovide a sim le. reliable and etiicient means lie dynamo.

In arrangements or constructions hitherto lmown or used for mounting a dynamo on the car or other vehicle, the dynamo has either-been mounted directly on the car The obbody are well known by those slcilled in the art and consist principally in theiactthat the pulleys or other driving means connccting the dvnamo and the car axle or wheel are i continually changing their relative positions 5 either because of unevenness in the track or road orby changes in the direction of the car. as for instance. in going around curves when the car body swings in relation to the i truck. For thesercasons this way of mounti ing the dynamos is not generally adopted in practice. \Vherc the dynamo has been carried .on the truck. elaborate supporting structures have been resorted to to support and hold the same securely in position. In such cases the dynamo has been carried in one of two positio s in relation to the end sill or beam of the truck. In one of these positions'the dynamo has been carried inside the truck, that is, between the ear axle and the l armature shaft of the dynamo: S represelgts end sill; iii the other position the dynamo is carried outside or beyond the end beam or sill of the truck. In the former of these positions, the dynamo is very inaccessible for adjustment, inspection, etc., and the space available is limited by the truck structure and particularly b the brake'meehanism so that it is'not o y difficult to mount the dynamo in this position but when mounted ,it is extremelv difficult to reach the same for inspection, adjustment, regulation, etc. In the latter position, that is, where the dynamo is mounted outside the sill of the truck, greater accessibility is obtained but at the expense of elaborate supporting structures and braces carrying and supporting the dynamo. Furthermore the dynamo being removed at a-distance from and outside its point of support there is great liability of sagging and getting out of alinement by reasoh of the jolting, shaking and twisting of the truck. Furthermore the drivin connection is re uired to be considerably longer than where t ie dynamo is carried inside the truck and this gives rise to a tendency of the driving connection to fly off the pulleys;

Ourinvention is designed to overcome these objections and to provide a simple 'form of mounting whereby the dynamo is carried in the most favorable position with regard to its support and the driving connection is shortened: and wherein the dy-' namo is easily accessible for the purposes of.

inspection. repair. regulation etc.

In the :tcconnmnying drawings. we have illustrated a lorm of mounting embodying our invention, in which Figure 1 represents an elevation with the parts shown in section. of a wheel. axle and truck of a railroad car or similar vehicle and showing the mounting of a dynamo with respcctt ereto, and Fig. 2a plan view of the l Sillllt.

Referring to the drawings. 1 repn-semsthe wiicclsand 2 the axle of the truck: It re iresent-s the truck frame and 4. the end sill or beam thereof; 15 represents the dynamo. ii a pulley secured to the axle 2 and mint ng therewith: 7 represents a ulley in alincmen! with the pulley B ,an scyured lfi'ille a driving connection between 6 and 7. s

-nally and centrally 0f the saddle to fit the assist in su porting the dynamo. Liners or .of the saddle 9 restsover and upon said dynamo frame 18. The dynamo is thus dynamo in normal position with respect to the driving pulley 6, means are provided said driving connection may be a chain or a belt, I 24 and the outer one preferably the former. In distinction from mounting the dynamo in the ways above referred to, we mount the dynamo so that its g weight or'centcr of gravity is vertically, or substantially so, below its place of support. Thus, in practically carrying out our invention, we support the. dynamo on the end sill of the car truck so that it is carried substantially vertically beneath said sill. In the drawings we have shown a form of mounting embodying our invention. for carrying a dynamo in the position stated as follows:

A suitable saddle shaped structure or casting 9 is fitted over the end sill or beam 4, this saddle being provided with a rectangular channel or recess .10 running longitudibeam 4. This casting or saddle structure may be firmly secured by means of bolts 11 passing throu li the sill or beam 4. Plates 12-are secured to thes'ides of thebeam 4 to stri s may )8 inserted between the plates 12 an the sides of the recess 10 to take up any looseness ofiit. The saddle is further supported by means of a pair of stay rails 1 '3 13, the. outer ends of which ass over the end sill or beam 4'and are r veted or otherwise secured to flanges formed on saddle 9. These stayrails l313 are preferably arranged to fit rabbeted portions 1414 of the saddle 9. The end flanges 15 of the saddle 9 come about flush with'the upper face of the beam 4, while the central portion beam. The inner ends of the rails 13 may be secured to any suitable and convenient portion of the truck. By this means the supporting saddle 9 is securely held on the beam 4 and no racking or twisting occurs. On each side of the saddle 9 are formed a ertures to receive rods 15-15 which may e in the nature of rock shafts, and to which are connected suspension links or arms 1616 at each end of each shaft. Said links or arms 16l6 may be free to swing on stationary shafts 15, 15 if desired, the object ham to obtain pivotal connection between links and the saddle. In the lower ends of said links or arms 16 are carried rods 1717 which pass through eyes 17 in the supported from the end sill or beam 4 and can yield, to a limited extent, to the movements of the car. In order to maintain the consisting of a yoke 19 formed on or secured to the rear links 16. A screw rod 20 is detachably connected to the dynamo and is provided with two adjustin nuts 22 and 23 threaded on the rod, the inner one 22 of which regulates the adjustment of a spring i 23 of which regulates the adjustment of a spring .25. Upon proper adjustment of the screw-nuts 22:23, the driving connection may be adjusted to the required tension and through the action of the springs the adjustment is maintained throughout the movements of the car, the springs 2425 acting to hold the dynamo in normal position. Rod 20 passes through a notch 20 in the crosspiece of yoke l9.'

By the above described arrangement and construction of mounting the dynamo, the

. weight of the dynamo is suspended directly beneath its place of support. the advantages of eliminating all e aborate and braced supporting structures which are. required when the'dynamo is carried either inside or outside of the sill, the obtaining of a shorter driving connection thereby eliminating the side whip or lasn of the driving chain or belt which occurs when this connection is lengthened as when the dynamo is mounted outside the sill, and the carrying of the dynamo in an easily accessible osition.

In order to obtain access to the ynamo, it is only necessary to remove the nut on the lower rear rod 17, remove said rod, .lift rod 20 out of the notch 20' and allow the rear end of. the dynamo to drop to the grounder to a suppor placed to receive it. The dynamo is thus easily accessible for repairing, inspection, regulation etc.

While I have shown and described specificaily one construction b which my invention may be embodied, I 0 not wish to limit. my invention thereby, as it will be evident to those skilled in the art that the invention is capable of-being embodied in various forms, and that modifications may be made without departing from the scope and principleof the invention.
